Zusammenfassung:The invention relates to a solvent-free sprayable condensed silicone sealant and a preparation method thereof.According to the solvent-free sprayable condensed silicone sealant and the preparation method thereof, through cooperation of an alpha-site functional group silane crosslinking agent and an organic tin catalyst, the silicone sealant can achieve rapid surface drying and film forming under the condition of low viscosity (high hydroxyl content); according to the present invention, the silicone sealant is prepared from the epoxy resin, and is matched with the non-volatile diluent for use, such that the prepared silicone sealant can meet the spraying process, can be rapidly subjected to surface drying curing at the normal temperature so as to form the compact polymer material film, can effectively prevent the corrosion of buildings and equipment, does not contain the volatile organic solvent, and is non-toxic and harmless to the human body and the environment. And the spraying effect is achieved. 本发明涉及一种无溶
